Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491606, here are decompositions:

13 + 491593 = 491606
67 + 491539 = 491606
79 + 491527 = 491606
103 + 491503 = 491606
109 + 491497 = 491606
229 + 491377 = 491606
277 + 491329 = 491606
307 + 491299 = 491606

Showing the first eight; more decompositions exist.
